- Is There Really a Disease Called "Hypoglycemia"?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: My sister-in-law claims that her many problems all arise from a
- condition called "hypoglycemia". Could you tell me if there really is such a
- disease and provide some information about it?

- ANSWER: More people think they have hypoglycemia than actually have it.
- Hypoglycemia is relatively rare and usually occurs only in diabetics who use
- insulin or other blood sugar lowering medications. However, it does occur
- occasionally in nondiabetics, and there are ways to test for it.
- Hypoglycemia is a condition where the levels of blood sugar (blood
- glucose), which the body needs for energy, fall too low. The symptoms are
- acute fatigue, restlessness, irritability, malaise, sweating, and weakness.
- Usually, we derive glucose from the food we eat. If we fast for a few hours,
- our body breaks down a substance called glycogen, which is stored in the
- liver, into glucose. When we fast for longer periods, our bodies metabolize
- stored fat into glucose. This way, through a complex system of chemical
- checks and balances, blood sugar levels are kept constant in healthy people,
- whether they are eating regularly or not.
- Diabetics have high blood sugar if they are not treated properly.
- However, if they are not careful about their diet or use of insulin and oral
- diabetic drugs, they may have occasional bouts of hypoglycemia because these
- drugs lower blood sugar too far. Oral diabetes drugs are called "hypoglycemic
- agents" because they lower blood sugar.
- Some nondiabetic people have faulty metabolic systems that cause
- occasional dips in blood sugar levels when they go without food. Other people
- have a metabolism which overreacts after a meal and produces too much insulin,
- which causes a sharp dip in blood sugar right after eating. In addition to
- metabolic problems, a possible cause of fasting hypoglycemia is an insulinoma,
- a benign tumor in the pancreas that produces excess insulin. Fasting
- hypoglycemia can also be due to alcohol abuse, especially when coupled with
- poor eating habits. Reactive hypoglycemia is less well understood, but is
- thought to be caused by abnormalities in the body's response to food.
- The common way to test for hypoglycemia is to have the patient fast for
- several hours and periodically check blood sugar levels. Although no one
- agrees exactly what a hypoglycemic blood sugar level is, the physician seeks a
- sag in the blood glucose levels that is relieved by eating. Another
- diagnostic test is to watch blood sugar levels after the patient eats a known
- amount of glucose. A third test is to watch the patient's blood glucose and
- insulin levels during a prolonged fast.
